Additional Safety for Disc Sanders

AVOID FINGER INJURIES. Never purposely

touch the moving sanding disc. Take care to
keep fingers away from sanding disc during
operations. If the workpiece is small or difficult
to hold, use a workpiece holding fixture. Sanding
abrasives can quickly remove large amounts of
skin!

AVOID WORKPIECE GRAB. Support the
workpiece on the work table against the rotation
direction of the sanding disc. Otherwise, the
sanding disc could grab the workpiece and pull
your hands into the moving disc.

AVOID KICKBACK. Avoid kickback by sanding
in accordance with directional arrows and
keeping the guard in place. Always sand on
the downward side of the disc—pay close
attention to the direction of disc rotation to avoid
placing the workpiece against the upward side
of the disc. Avoid sanding with excessive force.
Always keep the sanding disc guard installed.

ONLY SAND SAFE WORKPIECES. If there
is any doubt about stability or integrity of the
material to be sanded, do not sand it. Never
attempt to sand any sort of cable, chain, or wire.
If you do, entanglement can occur and cause
serious injury.

DISCONNECT POWER WHEN SERVICING.
Disconnect the machine from power and allow
the disc to come to a complete stop before
service, maintenance, or adjustments. Avoid
pulling cord-connected machinery by the cord—
instead, grasp the plug when disconnecting it
from power.

POSITION TABLE CORRECTLY. Make sure
the gap between the table and sanding disc
does not exceed
increases the risk of workpiece grab and pinch
injuries, while too small of a gap increases the
risk of sandpaper damage and restricts the
removal of dust during operation.

ONLY USE SAFE SANDPAPER DISCS. Never
use sanding discs that are damaged or torn; or if
the adhesive is not sticking firmly. If sandpaper
rips or comes off of the disc during operation,
the workpiece or your hands could become
entangled with the moving disc.

AVOID ENTANGLEMENT. Tie back long hair
and remove any loose-fitting clothing or jewelry
that could be caught up in the sanding disc or
other moving machine parts.

BE AWARE OF DUST ALLERGIES. Be aware
that certain woods may cause an allergic
reaction in people and animals, especially
when fine dust is created by sanding. Make sure
you know what type of wood dust you will be
exposed to in case there is a possibility of an
allergic reaction.

PROTECT YOURSELF FROM FINE DUST.

This machine puts fine dust particles into the
air during operation. Wood dust is harmful to
respiratory systems and long term exposure
may lead to severe health problems. Reduce
your risk by always using an adequate dust
collection system and wearing a NIOSH­approved respirator during machine operation
and for a short time after.

⁄16"—too large of a gap

Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre­cautions are overlooked or ignored, serious
personal injury may occur.

Model G0702 (Mfg. since 1/12)

No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per­sonal injury, damage to equipment, or poor
work results.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the avail­ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrican or
qualified service personnel in accordance with all
applicable codes and standards.

Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power

The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.

The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.

If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over­loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the requirements in the following section.

For your own safety and protection of

Note: The circuit requirements listed in this man­ual apply to a dedicated circuit—where only one
machine will be running at a time. If this machine
will be connected to a shared circuit where mul­tiple machines will be running at the same time,
consult a qualified electrician to ensure that the
circuit is properly sized for safe operation.

A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup­ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)

This machine is prewired to operate on a 110V
power supply circuit that has a verified ground and
meets the following requirements:
